Timeline of falling into a blackholeYeah, it seems reasonable that if you can feel a gravity gradient, blood would be pooling in your feet (assuming "head-up"), to some degree, eventually knocking you out. Whether the gradient is painful before then is up for debate perhaps? But how long a delay would the taller experience between these events is what I'm particularly interested in.

Timeline of falling into a blackholeI had imagined the mass of the black hole might even change the order of some of the events I listed in the question. @TidalWave suggests that you'd necessarily be dead by the time you cross the event horizon (if that's appropriate usage of that phrase...), but I wondered if a black hole could be big enough to have only a slight gradient at that point. Even if only in theory...
